Bon Appétit is an American food and entertaining magazine published monthly. It was started as a bimonthly magazine in 1955 in Chicago. The magazine was acquired by M. Frank Jones in Kansas City, Missouri in 1965. Jones was owner, editor and publisher until 1970, when Bon Appétit was merged into the Pillsbury Company, who sold it to Knapp Communications, publishers of Architectural Digest, four years later. Condé Nast Publications, the current owners, purchased Knapp Communications in 1993. Its sister publication was Gourmet, before the latter was discontinued in October 2009. The magazine's headquarters, which had been in Los Angeles, CA, were moved to New York City in early 2011.
